Nate Cole commented on AMBARI-5004:
-----------------------------------

YARN metainfo.xml defines two services, which means that each service will load the properties in the configuration directory.  In this case, YARN and MAPREDUCE2 will have matching config names.

> Now MR2 and YARN share the same folder in stacks/HDP/2.1.1/services/YARN, and a lot of (more than 50) YARN configs existed in MR2 service too. 
> eg. {code}
> GET /api/v1/stacks2/HDP/versions/2.1.1/stackServices/MAPREDUCE2,{code} there are properties like {code}yarn.resourcemanager.resource-tracker.address{code} ,etc.
> So these config properties should show up for YARN ONLY.
